T0 (ZZZ whom it may concern:

Be it known that I, EMIL G. JonANsoN, a citizen of the United States, residing at Rockford, in the county of l/Vinnebago and State of Illinois, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to improvements in a device for transmitting motion.

In the accompanying drawings, Figure 1 is a face representation. Fig. 2 is a top View. Fg. 3 is an isometrical representation of the stationary support. Fig. 4 is an isometrical representation of the bar 9. Fig. 5 is an isometrical representation of one of the disks 25.

ig. 6 is an isometrical representation of one of the links 19.

A support for the operative parts has a ed connection with the standard 1 andconsists of the horizontal portion 2, the extension 3, and the return-section 4. A stud 5 connects the outer end of extension 3 and one end of the return-section 4. From the return-section 4 extends a stud 6. 7 has a tubular extension 8, which receives the horizontal portion 2 of the support and is held in position to be rotated thereon. At four equal divisions of the disk 7 and near its periphery are pivoted the four bars 9, 1O, 11, and 12. Each of the bars has a'lengthwise slot 13, which receives the stud 5. To the free end of the return-section 4 and upon the stud 6 is mounted a spider, comprising the arms 14, 15, 16, and 17. To each of the bars is pivoted a link 19, which has a lengthwise slot 20, engaging the pins 21, extending from the bars 9, 10, 11, and 12. Each of the links has a plate 22, supporting a stud 23. The arms 14 and 16 each have an extension 24 and to the free end of which is pivoted a link 25. Its other end has a connection with the end of the bars 9 and 11 at their point of connection with the disk 7. As the support connected to the standard 1 remains stationary, the point 6, upon which the spider revolves, is fixed, also the stud 5, which guides the ends of the bars 9, 10, 11, and 12. As the disk rotates the bars 9, 10, 11, and 12 will move in their engagement with the stud 5, and by reason of the spider having a pivotal support on a different center than the stud 5 and the links 19, in conjunction with two links 25, forming a connection between A disk 7 the spider and bars 9 and 11, the plates 22 w1ll retain substantially a vertical position throughout their movements.

In the claims is mentioned a spider; but it is evident that a disk could be employed to support the links 19 and 25.

This device can be used in the construction of a feathering paddle-wheel by the employment of two like devices and connecting the plates 22 of one device by paddles with like plates of the other device.

I claim as my invention- 1. In a mechanical movement, a rotatable support, a fixed support located ofi the center of the rotatable support, a series of bars pivotally connected to the rotatable support and having a slidable engagement with the fixed support, a spider rotatable on a center diflering from the centers of the rotatable support and the fixed support, links connecting each of the bars with the spider, and a link connecting the spider with the rotatable 1soupportat the pivotal center of one of the ars.

2. In a mechanical movement, a rotatable support, a fixed support located oi? the center of the rotatable support, a series of bars pivotally connected to the rotatable support and having a slidable engagement with the fixed support, a spider rotatable on a center differing from the centers of the rotatable support and the fixed support, links having a pivotal connection with the spider and movable engagement with the bars, and a link connecting the spider with the rotatable support at the pivotal center 01" one of the bars.

3. In a mechanical movement, a rotatable support, a fixed support located oil the center of the rotatable support, a series of bars pivotally connected to the rotatable support and having a slidable engagement with the fixed support, a spider rotatable on a center differing from the centers of the rotatable support and the fixed support, links having a pivotal connection with the spider and movable engagements with the bars, and links connecting the spider with the rotatable support at the pivotal center of the bars.
